CRADLE-MOTOR FAN.

SPECIFICATION forming part of Letters Patent No. 640,703, dated January 2, 1900. Application led March 1,1899. Serial No. 707,317. (No model.)

To all whom it may concern/.-

Be it known that we, LUTHER G. ROGERS, AVERY C. BRUCE, JAMES C. ROBERTS, and FRANK A. RUSSELL, citizens of the United States, residing at Knoxville, in the county of Knox and State of Tennessee, have invented a new and useful Cradle-Motor, of which the following is a specification..

This invention relates to cradle-motors; and it has for its object to effect certain improvements in apparatus of this character whereby the same shall be rendered more eective and durable; and it has for its especial object the equipment of the apparatus with anovel fan attachment which provides means for automatically fanning the occupant of the crib during the rocking thereof.

For a full understanding of the merits and advantages of the invention reference is to be had to the accompanying drawings and the following description.

The improvement is susceptible of various changes in the form, proportion, and the minor details of construction without departing from the principle or sacrificing any of the advantages thereof, and to a full disclosure of the invention an adaptation thereof is shown in the accompanying drawings, in which- Figure 1 is an end view of a crib, showing the invention operatively related. Fig. 2 is a vertical central section of the head and foot portions of a crib, showing the relation of the invention. Fig. 3 is a detail plan view of the motor, the casing being in section. Fig. 4 is a section of the motor on the line X X of Fig. 3 looking in the direction of the arrow. Fig. 5 is a detail view showing the connection between the motor and the powertransmitting lever.

Corresponding and like parts are referred to in the following description and illustrated in all the views of the drawings by the same reference characters.

The crib 1 is mounted upon a platform 2 in the ordinary manner and has the middle portion of the rocker 3 connected with the intermediate portion of the base-bar 4 by means of a vertical standard 5, the latter constituting a brace and affording a convenient means of attachment of the fan-staff 6 with the crib. A coil-spring 7 connects each rocker of the crib centrally with a corresponding portion of the platform, and the terminal portions of this spring are rigidly attached' to brackets or plates 8, applied to the parts 2 and 3. These springs holdthe crib in position upon the platform and assist materially in the rocking movement thereof.

The spring-motor comprises a casing 9 of circular outline and a power-.spring and train of gearing located within the casing and protected and housed thereby. The train of gearingis disposed concentric with the powershaft 10, so as to occupy the least possible space, and may comprise any desired number of shafts and cooperating gear-wheels, according to the size and capacity of the motor. The spring 11 has one end attached to the power-shaft 10 and its opposite end secured to a convenient part of the casing or frame and is wound by means of a crank 12, fitted to a shaft 13, supplied with a pinion 14, meshing with a gear-wheel 15, secured to the outer end of the power-shaft 10. This construction admits of the spring being wound by the expenditure of a small vamount of force. The master-gear 16 is loosely mounted upon the inner end of the power-shaft and has a ratchet-and-pawl connection therewith in the ordinary manner, so as to admit of the spring being wound at any time without interference therewith on the part of the train of gearing. The last shaft 17 of the train of gearing is provided with a crank or wrist pin 18, from which the power for rocking the crib is taken.

The connection for transmitting power from the motor to the crib consists of a single lever 19, which is fulcrumed about midway of its ends upon a iixed support, which in the present instance is a stud or projecting part of the motor-casing 9. The lower end of the lever 19 has va slot 21, in which is iitted the crank or wrist pin 18, and the upper end of said lever is provided with a slot 22 to receive a pin 23, projecting outward from the body of the crib. The upper portion of the lever, intermediate of the fulcrum and the slotted end 22 is reduced, as shown at 24, to form a spring, which allows for the rebound of the crib at the end of each rocking movement IOO and which obviates jar and jolt and assists materially in the even movement of the crib.

A bracket 25 is securely fastened at its lower end to the platform, and its upper end, which is formed with a socket, receives the lower end of a standard 26, to which is pivotally attached the fanistaff 6. The upper end portion of the fan-stad is recurved,so as to overhang the end of the crib, and has a fan 27 attached thereto in any convenient manner, preferably by means of clips 28, so as to admit of an adjustment and the ready removal of the fan when required. The lower end of the fan-stan? is connected with the crib by means of a pin 29, the parts being constructed so as to admit of an oscillatory movement beingimparted to the fan-staff directly from the cradle.

The motor being Wound in the manner set forth and as Well understood, motion is imparted to the crib therefrom through the instrumentality of the lever 19, which is oscillated upon its fulcrum by reason of its eccentric connection with the motor-gearing in the manner set forth. p As the cradle rocks npon the platform the fan will have a vibratory movement imparted thereto directly from the crib by reason of the connections herein described. The motor is attached to a' convenient part of the platform and is arranged so as not to interfere with the monntings of the fan or the spring connection between the crib and platform, and this motor may be placed upon either the inner or the outer side of the platform, as may be found best adapted to the construction and disposition of the parts.

Having thus' described the invention, what is claimed as new, and desired to be secured by Letters Patent, is'- 1. In an apparatus of the class described, the combination with the platform, a crib arranged to rock upon the platform, and a motor applied to the platform, of a single oper ating-lever, fnlcrnmed intermediate its ends on a fixed support and having an operative connection at its lower end with the motor mechanism and at its upper end with the body of the crib, a fixed bracket attached to the platform at a point opposite the operatinglever, a stationary standard tted to and arising from the bracket, and a swinging fansta pivotally connected at its lower end directly to the crib-body and fulcrnmed intermediate its ends to the upper end of the stationary standard, said fan-stad being provided at its upper end with a laterally-oifset portion overhanging the crib and provided with a pendent fan-holder, substantially as set forth. y

2. In an apparatus of the class described, the' combination with the platform, a crib ar ranged to rock upon the platform, and a mo'- tor applied to the platform, of a single oper ating-lever 19 fulcrnmed intermediate its ends on a fixed support and having an operative connection at its lower end with4 the motor mechanism and atits upper end with the body of the crib, said operating-lever being provided intermediate the fnlcrum there of and its pivotal connection with the cribbody with a reduced spring portion adapted to yield and permit of the rebound of the crib at the end of each rocking movement, substantially as set forth.

In testimony that We claim the foregoing as onr own We have hereto affixed our signatures in the presence of two Witnesses.
